SANDPPERlNG-NIACHINE.

SPECIFICATION forming part of Letters atent No. 533,707, dated February 5, l 895.

Application tiled June 28,1893. Serial No. 479,074. (No model.)

To tl when?, it may concern:

Be it known that we, WILLIAM C. FULLER and THOMAS R. Care-TELL, of Dunkirk, in the county of Chautauqua, in the State ot New York, have invented new and useful Improvements in Sandpapering-Machines, of vwhich the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to certain new and useful improvements in sand papering heads, and consists of a sand-papering head upon which the sandpaper may be readily and easily replaced; and to that end our invention consists in the several new and novel features of construction and operation hereinafter described and which are specifically set forth in the claim hereunto annexed.

It is constructed as follows, reference being had to the accompanying drawings,in which-- Figure l, is a vertical section of the sandpapering head on line y y, Fig. 2. Fig. 2, is a cross section on line e' a, Fig. l.

The sandpapering head fB- comprises the bracket -D-, having the annular base -kand provided with suitable means for adjusting it vertically upon the shaft e-. The head proper, is constructed ot keystone shaped pieces 1yresting upon the base lc-having theirinner ends abuttingagainst the outer walls of the bracket -D- and are held in position by screws m. In the edge ot the head is -a transverse recess E- having parallel walls and in the inner end ofV loosened, to effect the ready removal of the saine. A padding is secured into the face ot said head,consisting'of alayer ot' rubber -n, a layer of felt -eo-f and an outer layer ot' canvas 1Q-1 In the outer face of said block a groove +l is cut, having inwardly converging walls and -G- is a filler, or grip, having its opposite sides beveled to tit into said groove and said screws -2- pass through it and retain it in position.

To secure the sand-paper upon the head, we loosen the screws -2- until the filler -G may be freely removed from the`block. W'e then place one end ofthe sandpaper between the filler and the block, drawing the sandpaper tightly arou nd the periphery ofthe head until its opposite end may be inserted between said filler and the block, when the screws are again tightened until the filler has drawn the sand-paper tightly about the head.

6, is a piece of metal inserted in the opposite side of the sand-papering head to counterbalance the weight caused by the block --F-.

What We claim as our invention, and desire to secure by Letters Patent, is-

A sand papering head comprising a cylindrical body having a rectangular recess transverse toits periphery, the block fitting in said recess and having lateral ribs engaging guide grooves in the walls of said recess, a bevel edged grip or tiller fitting in a correspondingly shaped seat or recess in said block, screws having their unthreaded portions passing through apertures in said block and grip or .tdler and having their threaded 4portions engaging nuts held in the-bottom ot said recess, and springs arranged on said screws and pressing against said block, substantially as set forth.

In witness whereof we have hereunto set our hands this 24th day of June, 1893.

W. C. FULLER. THOMAS R. CAPWELL. In presence of- LEsTER F. STEnENs, ELTON D. WARNER.
